Abstract
A high-intensity pulsed electric field (HIPEF) vitrectomy apparatus is disclosed. An exemplary apparatus includes a HIPEF probe comprising at least one electrode disposed at a distal end of the HIPEF probe, such that the distal end is configured for insertion into an eye. Various embodiments include a probe shaft assembled from a modular end segment and one or more additional modular shaft segments, each of the modular end segment and one or more modular shaft segments in turn comprising at least two longitudinal channels adapted to accommodate an electrode unit. In some of these probe shafts, each of the modular end segment and one or more modular shaft segments has a central longitudinal channel, and the probe shaft further comprises an aspiration tube disposed within the central longitudinal channel.
